Featured bridges are: Big Four Railroad Bridge (KY); Germantown Covered Bridge (OH); George Street Bridge (IN); Virgin River Bridge (UT); Bryan Bridge (NE); Brush Creek Bridge (KS); Natchez...
Boston's Commuter Comeback
More than 30 years after its abandonment, the Old Colony Railroad in Massachusetts is being revived through a �480 million rehabilitation project to serve residents southeast of Boston....
An Intelligent Robotic Vehicle for Lunar/Martian Applications
This paper describes the research effort being undertaken at UA/NASA Space Engineering Research Center (SERC) towards a general-purpose intelligent robotic vehicle system (IRVS) for Lunar...
An Overview of the Accident Response Mobile Manipulation System (ARMMS)
The development of a high mobility platform integrated with high strength manipulation is under development at Sandia National Laboratories. The mobility platform used is a High Mobility...
A New Robotic System Concept for Automating Highway Maintenance Operations
The purpose of this paper is to present the Tethered Mobile Robot (TMR) concept, a new robotic system for automating highway maintenance operations. The operational requirements of this...
Snap Buckling of a Delaminated Layer in a Composite Cylinder
We investigate snap buckling of a thin delaminated layer on the inner surface of a contracting thick cylinder. Finite-deflection solutions of the layer with or without considering the...
Late Stage Damage in G30-500/PMR-15 Laminates
Damage progression has been studied experimentally under tension using [02/906]s...
Implementation of a Viscoplastic, Kinematic Hardening Constitutive Model for Impact Prediction
This paper reports on a preliminary study to determine the significance of the Bauschinger effect on modeling impact and other large deformation events. Such events have significant implications...
Logistics Carriers for the First Lunar Outpost
This paper describes that aspect of logistics concerned with the design parameters and operation of hardware that may be used to deliver and protect spares and resupply items for NASA's...
Oxygen Generation from Synthetic Moon Soil Using a Plasma Reactor
A series of experiments were performed to evaluate the potential for generating oxygen from silica powder, alumina powder and a synthetic moon soil powder. A non-transferred arc plasma...
Lunar Oxygen Production in a Hydrogen Cold Plasma
This paper examines the concept of oxygen production from unbeneficiated lunar regolith using a non-equilibrium or 'cold' hydrogen plasma. An experimental investigation has indicated that...
Efficient Path Planning Strategies for Unmanned Rover Vehicles
Path planning strategies are studied using an optimization model. Four main sub-models are discussed that contribute to the computing of minimum energy vehicle path planning. These are:...
A Minimum Mars Mission Approach
The purpose of this paper is to identify the mission architecture required to perform a human exploration mission to Mars using a minimum amount of resources. This mission will send three...
A Surface Exploration Vehicle Testbed for Real-Time Control Exerimentation
Current mission scenarios for return to the moon as well as Mars include some robotic systems; for the precursor unmanned mission, these systems will be required to operate under autonomous...
Transfer Vehicle Sizing for Missions to Mars
The purpose of this study is to analyze the interactions between mission and vehicle design parameters, and determine how the selection of a particular trajectory and transit time affects...
